'Dexter' shock preview: Debra's sex and drugs spiral

We warned you Debra was going down a dark path this season.

Below is an exclusive first look at Deb’s opening scene from the premiere of Dexter‘s final episodes. Picking up six months after the by-the-book police lieutenant killed her boss, Debra (Jennifer Carpenter) has quit Miami Metro. Not surprisingly, she’s a little messed up. In fact, this scene in a cheap motel is Deb like you’ve never seen her before. And it’s just the beginning of her story this year.

Season 8 starts on Sunday night on Showtime. For more details on the season, including Debra’s descent, check out our Q&A with showrunner Scott Buck. And sure to come to EW.com after the premiere for the revival of our Dexter recaps. Here’s your clip:
